Two men were charged with first-degree murder Monday in Madison County Circuit Court in connection with the shooting death of 23-year-old Travon O. Bey of East St. Louis.

Gregory Crowder, 49, of East St. Louis and Derrick L. Coleman, 24, of Madison face four counts each of first-degree murder. Both men were also charged with aggravated unlawful possession of a weapon by a felon.

Crowder and Coleman are being held in the Madison County Jail.

Authorities are trying to locate a third individual identified as Derrick Coleman's brother, Robert L. Coleman, 21, formerly of East St. Louis, who may have witnessed Bey's shooting.

The St. Louis Metropolitan Major Case Squad was activated at the request of the Madison Police Department after responding to a 911 call of a shooting victim at 4:30 p.m. Saturday in the 2000 block of Fifth Street.

The Madison Police Department arrived and found a victim, identified as Bey, who suffered gunshot wounds while inside the residence. Bey was treated at the scene and transported to a local hospital where he was pronounced dead.

Investigators with the Major Case Squad identified Crowder as a suspect in the case and took him into custody at approximately 2:20 a.m. Sunday in East St. Louis. Crowder was armed when investigators took him into custody.

Crowder was convicted of voluntary manslaughter in 1985 in Sangamon County, Ill. He was also convicted in 2007 of unlawful possession of a weapon by a felon in St. Clair County.

The investigation into the shooting revealed that Coleman had possession of a firearm in the residence. According to police, Coleman provided a firearm to Crowder while inside the residence. Bey was inside the residence prior to the shooting. Authorities said Bey and Crowder knew each other and have had issues with each other in the past.

Crowder approached Bey in the residence and eventually used the firearm to shoot Bey fatally, police said. Crowder removed property from Bey after the shooting. Crowder then fled the residence with Coleman in a green 1999 Ford Expedition. The vehicle was found abandoned during the early morning hours Sunday in Granite City.

Coleman came to the Granite City Police Department voluntarily, at approximately 2:30 a.m. Sunday, knowing investigators wanted him for questioning. Coleman was subsequently taken into custody.

Robert Coleman is wanted by the Granite City Police Department for aggravated battery. The charge against Coleman is unrelated to the investigation into Bey's death, and was issued on April 10. Investigators were told that Coleman was aware of the warrant and fled the scene of the murder.

Anyone with information on the whereabouts of Robert Coleman is asked to contact their local police department.
